Building a Stroker!!!
Well, I bought a 4.2 on a stand awhile back ($60) for building a stroker. I finally went to the junkyard and pulled a 4.0L from a 94 Cherokee (2wd, sad) for $130. Now to start the rebuild! The 4.2 I purchased had a blown piston so I hope that I can use the crank. The 4.0 I pulled had a head gasket blow so it should be good to rebuild, although I want to bore it out. Not sure who can bore an engine around Indianapolis but I want some more horsies. Any suggestions? I was planning on doing a simple 4.5L build...
4.5L Low-buck simple stroker
~ Jeep 4.2L 3.895" stroke crank
~ Jeep 4.2L 5.875" rods
~ Jeep 4.0L 3.875" standard bore pistons
~ CompCams #68-231-4 206/214 degree camshaft
~ Ported HO 1.91"/1.50" cylinder head
~ Stock 0.051" head gasket
~ 0.081" quench height
~ Ford 24lb/hr injectors with adjustable FPR or MAP adjuster for '87-'95 engines, Ford 24lb/hr injectors with stock 49psi FPR for '96 and later engines
~ 260hp @ 4850rpm, 321lbft @ 3500rpm
Seems simple enough, any suggestions? Other than taking pictures which I do plan on doing!!!
Seriously you make that sound easy. Keep us updated on this. What kind of torque/hp ratings do you figure that stroker will put out?
First problem reached. I started to work on the new engine I pulled when I realized that the engine has seized up, I cant rotate the flywheel to start the take down process! So with that said I cant put it on my engine stand.
Soak that sucker in some Pb and try to turn it with a impact
